PW - <br />San <br />San Miguel River - Data for sites SW -N217 (up gradient) and SW -N218 (down gradient) have <br />been complied and are shown on the summary tables below and graphically. Please note that at <br />SW -N217 and SW -N218 the only constituents that are sampled for include lab pH, lab electrical <br />conductivity, total dissolved solids, dissolved iron, total iron, total manganese, and acidity. <br />These two sites differ from all the other sampling locations. <br />Summary tables for all parameters are provide below for each site and include data from 2008 to <br />the end of September of 2017 if available. Please see Appendix 2.05.6(3)-3 for additional <br />information. <br />t ,Iwo'kinvi) <br />`tJJ <br />1V! <br />JVV <br />VIV <br />1 /V <br />al 1WAIT <br />J/G7/1J <br />iron, din 0141 /1) <br />0.04 <br />0.05 <br />0.21 <br />0.22 <br />0.01 <br />5/27/15 <br />8/23/12 <br />hXMI tow (mgt!) <br />4.85 <br />12.48 <br />54.01 <br />54.10 <br />0.09 <br />8/27/1.3 <br />2/12/15 <br />Acidity CaCO3 (mg/1) <br />5.0 <br />0.0 <br />0.0 <br />5.0 <br />5.0 <br />3/20/12 <br />3/20/12 <br />Manganese (mg/1) <br />0.154 <br />0.246 <br />1.134 <br />1.160 <br />0.026 <br />8/27/13 <br />8/19/14 <br />TSS (mg/1) <br />250.7 <br />797.0 <br />3647.5 <br />3650.0 <br />2.5 <br />8/27/13 <br />2/12/15 <br />SW N218 <br />Parameter Mean Std Range Max.
